VPN with ip negotiated

[c.soares]

Hi, everybody!!

I want to configure a VPN with IPSEC. I have a router with a IP given by my ISP and never change, and in the other end point I have a router with a IP negotiated by the ISP that can change every time I go to the internet. I have configured the routers with IPSec static and dynamic. This don't work. I have use TED (terminal end-point discorery) and don't work.

What should I do to configure this possible scenario.

Thanks on advance !!

Help please..

You must use the next comand lines in the router with the static Ip address.

crypto isakmp key "cisco123" address 0.0.0.0 0.0.0.0

crypto ipsec transform-set Myvpn esp-des esp-md5-hmac

crypto dynamic-map VPDN 1

set transform-set Myvpn

crypto map STATICVPN 10 ipsec-isakmp dynamic VPDN
